Ambilineality is a cognatic descent system in which individuals may be affiliated either to their father's or mother's group. This type of descent results in descent groups which are non-unilineal in the sense that descent passes either through women or men, contrary to unilineal descent, whether patrilineal or matrilineal.
An example of an Ambilineal lineage. In ambilineal lineage, descent is traced through either the maternal and/or the paternal lines, usually meaning that the individuals choose whether to affiliate with their mother or their father's group, or both. [14] [15] Ambilineal lineage can be bilineal or bilateral.
There are four main headings that anthropologists use to categorize rules of descent. They are bilateral, unilineal, ambilineal and double descent. [9] Bilateral descent or two-sided descent affiliates an individual more or less equally with relatives on his father's and mother's sides. A good example is the Yakurr of the Crossriver state of ...
A lineage is a single line of descent or linear chain within the tree, while a clade is a (usually branched) monophyletic group, containing a single ancestor and all its descendants. [3] Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, and ...
Omaha kinship is the system of terms and relationships used to define family in Omaha tribal culture. Identified by Lewis Henry Morgan in his 1871 work Systems of Consanguinity and Affinity of the Human Family, the Omaha system is one of the six major kinship systems (Eskimo, Hawaiian, Iroquois, Crow, Omaha, and Sudanese) [1] which he identified internationally.
In biological phylogenetics, a clade (from Ancient Greek κλάδος (kládos) 'branch'), also known as a monophyletic group or natural group, [1] is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. [2]
Hawaiian kinship, also referred to as the generational system, is a kinship terminology system used to define family within languages.Identified by Lewis H. Morgan in his 1871 work Systems of Consanguinity and Affinity of the Human Family, the Hawaiian system is one of the six major kinship systems (Inuit, Hawaiian, Iroquois, Crow, Omaha, and Sudanese).
The system is associated with groups that have a strong tradition of matrilineal descent. In doing so, the system is almost a mirror image of the Omaha system, which is patrilineal. As with the Iroquois system, the Crow uses bifurcate merging, meaning that there is a distinction between collateral relatives of different gender in Ego's descent ...
